The winning features of the ATRIUM SP® komfort in the world of sliding windows are its unique soft-close mechanism and its night vent facility.

With just one turn of the hand, the sash is unlocked, opened and conveniently moved.

And the energy expended in the process is stored. When it is manually slid to the closed position, this stored energy is used to retract the sash into the frame opening childs play, just like a drawer.

The integrated all-round night vent airing facility enables draught-free, steady and natural basic ventilation which helps to avoid the formation of mould. Turning the handle through 180° moves the sash approx. 6 mm away parallel to the frame. In this position the window is secured by the locking system and can be equipped up to burglar resistance class RC 2. This means that rooms can be conveniently ventilated even when you are not at home.

The ATRIUM SP® komfort has bogies and a stay system with an opening width of up to 125 mm for highly heat-insulated window systems.
